Last updated on SEPTEMBER 25, 2020

Applies to:

Oracle WebLogic Server - Version 10.3 and later
Information in this document applies to any platform.


Different behavior may be observed if Webservice is invoked via JAX-RPC Service Control versus XML Bean Service Control.

With JAX-RPC Service Control, an exception may be thrown during the unmarshalling process from a SOAP response to  JAX-RPC Web Service Classes.

This exception is thrown for some types:

<faultstring> cannot be cast to java.math.BigInteger</faultstring>
<bea_fault:stacktrace xmlns:bea_fault="">java.lang.ClassCastException: cannot be cast to java.math.BigInteger
at com.bea.staxb.runtime.internal.IntegerTypeConverter.print(
at com.bea.staxb.runtime.internal.SimpleContentBeanMarshaller.print(
at com.bea.staxb.runtime.internal.RuntimeBindingProperty.getLexical(
at com.bea.staxb.runtime.internal.PushMarshalResult.writeCharData(


Upgrading from WLS 8.x to 10.3.0.
